The Yeti Pro can record up to 192 kHz/24-bit, while the Yeti tops out at 48 kHz/24-bit. The Pro model has the capability for a stereo analog XLR connection, in addition to the digital USB that both have. Otherwise, they're very similar.

According to Blue Microphones THX is not certifying any microphones in alte 2011 2012 time frame and phasing out the THX logo usage on microphones. Blue Microphones states that Yeti Por has same or better specs than Yeti with THX logo just that THX no longer offers THX logo licensing etc for microphones. You will find similar info if yoiu do a Google search for Yeti Por microphone. I have one and am just getting started using it for podcast and screencasting. I plan to test it with iPad to see if it works.

I have a AKG condenser mic and a audiobox USB from PreSonus and I use a headphone connected to my pc (using Windows and Audacity), and I cannot set latency to ZERO... It's impossible to listen to myself while singing... I just want to know if I'll have this problem with this one... And if is necessary to use audiobox to record the sound?

There are videos all over You Tube and the Net that show people using an Apple camera USB adaptor and the Yeti without any issue. I plan to try it myself.

I notice another people has posted an "absolutely not" reply. I'm not sure why that is. Has he tried to connect and failed? Also if he did, was it an Apple USB adaptor or another brand? I know when the update came for the iPad, some third-party USB connectors failed to operate. Not so with the Apple branded product.

Maybe people should not assume things don't work until they try them. The hundreds of videos I've found on the iPad and Yeti make it clear that you can connect and record with very good quality.
